Overprints are distorted 

PROBLEM REMEDY

 

1. Overprints 

are 

distorted. There are 
irregular ink splashes 
or ink dots overlap each 
other as shown in the 
example on the right. 

When the print head is hit by a moving object, it may get 
repositioned. See the example below: 

 

Such overprints are made when the distance between the print head 
and the object is too big. Move the head to the object plane at the 
distance of less than 

15mm

. If this is impossible, adjust 

electromagnets within the head to print over a greater distance - see 
paragraph 

Adjusting valve electromagnets in electromagnetic 

heads

 above. Overprints made at different distances between the 

front of the head and objects are shown below. 

 

The distance between the head and object is 

6 mm

, 

 

The distance between the head and object is 

10 mm

, 

 

The distance between the head and object is 

15 mm
